New Week 5 – 7.5 FTC

Step 1: Week 5 kickoff meeting – Monday 10:10 am

  • Join us for the weekly live meeting and lecture via the link in Canvas
    (or watch the recording later)
  • Agenda: Logistics, note changed Thursday time for this week (oops, update: now it is changed back to the usual 4-6pm time!), lecture/discussion about the Fundamental Theorem of Calculus, why it is true, and how to use it to solve definite integrals.

Step 2: Get started on the WebAssign homework

  • Log into WebAssign from Canvas and start the Section 7.5 homework
  • Be sure to use the e-book when you need help and to look at relevant definitions, theorems, and examples
  • All of the problems in this homework assignment are computations of definite integrals using the Fundamental Theorem of Calculus.
  • Problems 1-2 and 4-6 are about using the Fundamental Theorem of Calculus to solve definite integrals involving relatively simple algebraic functions. Many of the integrands will need to be simplified or rewritten before antidifferentiation rules can be applied.
  • Problems 3 and 7 are about the same thing, but with exponential functions. Again, some preliminary algebra/rewriting may be useful.
  • Problems 8-9 are about the same thing, but with trigonometric functions.
    • Example 2(b) provides an easy starting point; often for these types of problems the hardest part is remembering how to evaluate the trigonometric functions after anti-differentiating.
    • Theorem 7.18 from the previous section has the antidifferentiation formulas that you may need for these types of problems.
    • This Khan Academy video on the Definite integral of a trigonometric function goes more in depth and has a more challenging evaluation step at the end.
  • Problems 10-13 are where things start to get tricky; you may need to consider logarithmic functions, inverse trigonometric functions, and even guess-and-check techniques with the reverse chain rule. This is where what you learned in the previous section will come into play; if you get stuck, try reviewing the reading and recommended videos for Section 7.4.
    • See Theorem 7.16(b) in the previous section for logarithmic antiderivatives.
    • See Theorem 7.19(a) and (b) from the previous section for inverse trigonometric antiderivative formulas.
    • See Theorem 7.21(c) from the previous section for the reverse chain rule formula.
  • IMPORTANT NOTE – The Section 7.5 Mastery Quiz problems will be based on the problems above but not all of them will ask for numerical final answers. Some problems will ask you things about how you solved these problems and the techniques that apply to different types of problems.

Step 3: Take a break

  • We keep on keeping on. Take a break, laugh at something, talk to somebody, pet your cat. Then get back to it. You can do this.

Step 4: Get help if you need it… and finish the homework

  • *USUAL* TIME THIS WEEK AFTER ALL – Zoom drop-in 4-6pm Thursday (link in Canvas)
    • Or, if you can’t attend, watch the recording (link to be added in Canvas later)
    • Agenda: Discuss wekly updates, get math help, ask Dr. Taalman anything
  • FUN EXTRA OPTIONAL EVENT – I’m giving a talk “at” Willamette University at 7:10pm EST that day; it’s online and you can come to the talk if you want to (or not, I’m not keeping track. It’s about Coding and Generative Design for 3D Printing.
  • If you need help now or at any point: For math questions, use Canvas Chat or Discussion, or contact the SMLC. For other questions text Dr. Taalman directly.

Step 5: Take the Mastery Quiz for Section 7.5

  • When you’re ready, take the 7.5 Mastery Quiz in Canvas (and retake if needed)
  • I recommend you take your first quiz attempt by Friday or Saturday
  • Click here to read details about quizzes - read BEFORE ATTEMPTING any quiz
    • The rules for Mastery Quizzes are now different. For each section in Chapter 7 you will have exactly two opportunities to take the quiz for that section, and both of those attempts need to be completed in Canvas by the end-of-week deadline of 11:59pm on Sunday.
    • (For retakes of previous quizzes, I am working on a solution that I will announce in about a week. Most likely you will get a fixed amount of retakes for previous quizzes. The final exam structure will be announced later, but optimally will also consist of Mastery Quiz retakes.)
    • During each attempt you will have 15 minutes to answer three questions. The questions will appear one at a time and you will not be able to go back to previous questions. You will be able to see your quiz responses only one time, at the very end of the quiz.
    • As always, the quiz questions are randomized from a large bank of problems that are based on the homework assignments. This means that your second-attempt quiz will likely have completely different problems than your first-attempt quiz, which means that the best way to prepare for your retake is to study the homework assignments.
    • I strongly recommend that you wait at least 24 hours after your first quiz attempt before attempting your one and only retake for that section; therefore you should try to take the quiz the first time by Saturday afternoon so that you have time to take the retake on Sunday before the 11:59 pm deadline.
    • You are on your JMU honor to complete each quiz without any outside assistance; no calculators, computers, phones, or any other technology or help from other people.
    • Because other students will take quizzes at different times, you are also on your honor to not share any information about any quiz or its contents with anyone else. I will take honor violations very seriously; your respect for the JMU honor code will allow us to complete this course online. Thank you for making this possible.

You must finish the WebAssign homework and both quiz attempts before 11:59 pm on Sunday — but having said that, these are not normal times; please just text me if you need an extension due to personal, economic, or family situations.

Let me know how things are going by filling out this End-of-week-5 Survey.

Have a good week everyone! Please don’t hesitate to contact me if you need anything.
